Currently available options such as amber alerts and the presidential alert are reported to be very slow.

The ShakeAlertLA is a pilot project, in collaboration with the US Geological Survey (USGS), AT&T and The Annenberg Foundation, that combines the USGS ShakeAlert earthquake early warning sensor network with mobile app technology.

The app is developed in open source, which allows it to be replicated by other cities, counties, and states.

Here’s how the new #ShakeAlertLA works-the farther away from the epicenter..the longer the warning..Seismic “P-Waves” (or primary waves), on average, travel about 4 miles per second-Therefore, if you are 20 miles from the epicenter you will receive about a 5 second warning @FOXLA
